- 1). Convert the first equation into slope-intercept form, or y = mx + b
For example, if your first equation were 2x + y = 8, you would convert it to y = -2x + 8. - 2). Convert the second equation to slope-intercept form.
- 3). Graph both equations by entering them into the graphing calculator and using the "graph" function.
- 4). Locate where the two lines intersect one another on the display. The X and Y coordinates where the lines intersect are your solutions to the linear equations. The process will vary depending on the type of graphing calculator you have. If you can't find an "intercepts" function in your calculator, consult your documentation for where the function might be.
